Details on her character are being kept under wraps, but TVLine has learned that she will be playing a pivotal new character. (Could she be Coop and Annie’s daughter?)

Seyfried will appear in multiple episodes, making it her biggest TV gig since Big Love ended in 2011. Though she is best known for her film work these days, Seyfried’s TV resume also includes roles on Veronica Mars, Wildfire, All My Children and As the World Turns.

Twin Peaks co-creators David Lynch and Mark Frost have penned all episodes of the present-day continuation — which will total more than the originally announced nine hours — with Lynch directing every installment. Filming is currently underway in Washington state.

At the Television Critics Association summer press tour in August, Showtime president David Nevins hinted that fans can expect “familiar faces” to join returning cast member Kyle MacLachlan. “You should be optimistic that the people that you want [back] will be there, and then there will be some surprises in addition.”
